Check out some of the feedback we have received from recent customers.

“I just wanted to say that we love the new windows. The combination of sound and weather protection is terrific. It is an odd experience not to realize when it’s raining, because we can no longer hear the rain and the difference in the street noise. This fix done by Wayne to the seals seems to have totally solved the initial problem.”
